Abstract

PURPOSE
We present an atypical case of calcific tendinitis of the shoulder with intraosseous loculation.
MATERIALS AND METHODS
A 59 year-old female complained of acute exacerbation of chronic left shoulder pain and restricted range of motion. Simple radiographs showed a subacromial calcific deposit and magnetic resonance imaging revealed cortical erosion with intraosseous extension of calcific material mimicking infection or tumor. She was managed with arthroscopic excision of the calcific deposit, curettage of the intraosseous lesion and subsequent rotator cuff repair with a suture anchor.
RESULTS
Her acute pain promptly subsided. Her rehabilitation was uneventful and she gained full range of motion. Radiographs five months after the operation showed no recurrence of calcific material.
CONCLUSION
Calcific tendinitis of the shoulder can present with a variety of images involving the adjacent bone. The correct recognition of this disorder may avoid unnecessary investigation and treatment.
